513 on rIfx (genCmp was broken)
515 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
517 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
518 * src/z80/main.c (_keywords[]),
519 * src/SDCCglobal.h (struct options),

523 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
524 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
525 always available in leading double underscore form. The C99 support is
526 mostly missing, but it's a start.

576 2005-03-20 Borut Razem <borut.razem AT siol.net>
578 * support/scripts/inc2h.pl: WIN32 port

604 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
606 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
608 * device/lib/printf_large.c: removed inline assembly for portability and
609 readability. Use printf_fast if speed or size are more important.
610 * src/pic16/gen.c: removed conditions around use of DEBUGpc
611 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
613 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
615 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
616 prevent compiler warning
618 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
620 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
621 moved to level 0 and declared as static. Also they are explicit
622 placed in access bank. This was necessery because some times they
623 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
624 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
625 optimizations. Currently only compare to unsigned char is implemented,
626 * src/pic16/gen.c: added fReturnIdx array,
627 * (struct resolvedIfx) is moved to gen.h and made public,
628 * (struct _G): added sregsAlloc and sregsAllocSet fields,
629 * (aopForSym): added an optimization to directly store in stack of
630 the operand of a SEND iCode,
631 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
632 but as registers instead (AOP_REG) using the fReturnIdx array,
633 * (pic16_freeAsmop): remove the freed register from the
635 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
637 * (pic16_popGetTempRegCond): changed function prototype, now
638 function takes also a bitVector argument v which holds the current
639 set of registers that are allocated for stack access by aopForSym,
640 registers allocated in aopForSym for accessing stack symbols are not
641 any more part of the functions usedRegs field,
642 * (genCall): some times aopOp is called for a stack variable to be
643 send, aopForSym might perform the push, if this is true make sure
644 that genCall doesn't push the variable twice by testing _G.resDirect,
645 * (genFunction): changed testing for unspecified interrupt number
646 from 256 to INTNO_UNSPEC,
647 * modified selection scheme of frame pointer generation. Previously
648 if function did use local registers a frame pointer was generated,
649 now a frame pointer is generated only if function has arguments
650 (that need PLUSW2 register access), or has stack arguments, or the
651 compiler is not instructed to omit the frame pointer,
652 * (genEndFunction): before restoring local registers that were saved
653 in the function preamble, also restore the registers that *might*
654 have been allocated for stack access,
655 * (genRet): removed some old comments,
656 * (genCmp, the active (RN's) version): added a call to the
657 pic16_genCmp_special function to perform the compare with a more
658 robust and optimized way,
659 * (genInline): a feature has been added in inline code generation,
660 which allows a wildcard variable substitution when writing inline
661 assembly. Code is incomplete and experimental therefore undocumented,
662 * (genCast): changed order of aopOp for result and right to allow
663 aopForSym to directly load the result if possible,
664 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
665 perform an optimized compare on some selected special occasions,
666 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
667 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
668 generate an IVT any more,
669 * src/pic16/main.c (pic16_optionsTable): added command line option
671 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
672 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
674 * src/pic16/NOTES: Raphael Neider added in list of active developers
675 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
676 jumptable_end to prevent bug #,
677 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
678 inCond and outCond fields,
679 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
680 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
681 turn off register spilling,
682 * (packRegsForOneUse): synced with other ports' versions although it
683 is not used currently,
684 * (pic16_packRegisters): added an optimization while reading
685 structure bitfields, some registers may be saved (malloc code is
686 decreased by 80 bytes)
688 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
690 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
691 left is a bitfield, if yes, then don't optimize assignment. Perhaps
692 this can be optimized more?
694 2005-03-10 Raphael Neider <rneider AT web.de>
696 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
697 genNearPointerGet): (hopefully) fixed access to bitfields via
698 pointers (p->bitN = x; and x = p->bitN; failed)

744 to keep the correct label reference count when adding/removing references
745 to labels. A peephole file using this is appended to patch #1144962.

888 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
889 this might fix SIGSEGVs on MinGW...
890 * src/SDCCopt.c (killDeadCode): restored original behaviour
891 (volatile operands might get thrown away though)
893 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

1332 Adding support for replacing ljmps with sjmps in jumptables
1333 generated for switch statements. For now you need to set the
1334 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1335 Now 4 algorithms for mcs51 jumptable generation are used:

1357 * src/pic16/genarith.c,
1360 * src/pic16/pcode.c: applied patches #1068154 and #1070213
1362 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
1364 Large cummulative patch for pic16 port.
1365 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1366 to call when a stack overflow occurs,
1367 * (malloc.h): added CVS Id tag,
1368 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1370 * added libc directory. The current version of LibC contains string
1371 functions, ctype functions and macros and some functions of the
1372 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1373 be extensively tested in the future. Standard disclaimer here.
1374 Library is not automatically build yet. But one can build it by
1375 invoking 'make' inside the libc directory.
1376 * added ADC library under libio. Preliminary version yet.
1378 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1379 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1380 aopForRemat() now and not by pic16_aopOp(),
1381 * (pic16_popGetTempReg): removed warning messgae when allocating
1382 temporary registers, its a buggy feature and will be removed,
1383 * (pic16_popGet): set register instance field in AOP_CRY,

1385 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1386 * (pic16_storeForReturn): optimized return of 0,
1387 * (genCmp): experimental code for new genCmp which uses PIC18's
1388 special compare&skip instructions. Initial tests fail some times
1389 with variables grater than 1 byte in size, so new code is disabled,
1390 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1392 * (genCast): began a fix to optimize the casting of a bit to another
1393 bit, now assigning a bitfield to another bitfield will fail, sorry,
1394 * src/pic16/main.c: disabled the use of lr-support feature,
1395 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1396 * added some function prototypes, added function _debugf prototype,
1397 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1398 bits with offset (case PO_GPR_BIT),
1399 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1401 * (isBankInstruction): modified to return 0 for no banking instruction,
1402 and 1 for banking instruction,
1403 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1404 caused stop processing pCodes after a inline assembly block,
1405 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1406 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1407 registers when it shouldn't,
1408 * src/pic16/ralloc.c (allocReg): add preliminary support for
1409 supporting a limited set of temporary registers,
1411 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1413 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1414 genDataPointerSet): ensure assignments always copy in MSB to LSB
1416 (loadRegFromAop): recognize CLRH optimization,
1417 (genFunction): optimize RECEIVE iCodes in reentrant functions
1419 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1421 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1422 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1424 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4419 loaded with the linker search paths (-L arguments) and the libraries
4420 to be linked with the current source (-l arguments). Changes
4421 currently will affect only the pic16 port.
4422 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4423 include path the port specific paths and port specific libraries,
4424 * gplink command now contains the $3 argument,

4440 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4442 Documenting changes from previous commits.
4443 * configure.in (version 1.56),
4444 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4445 when generating output files to configure the pic16 library,
4446 but now I've commented it out, since gputils aren't installed in the
4447 SF compile farm, so library won't compile
4449 * device/lib/Makefile.in (version 1.56): initially I've added in
4450 target 'all' the prerequestive 'model-pic16' so it compiled the
4451 pic16 library, but now I've commented it out for the same reasons
4453 * added targets 'model-pic16' and 'objects-pic16' to compile the
4455 * added target 'port-specific-objects-pic16' to handle the
4456 generated libraries and copy them into the build/ directory
4457 * added target 'clean-intermediate-pic16' to clean intermediate
4458 files into pic16 directory
4459 * in target 'installdirs' added line to create directory pic16 in
4460 the installation path
4462 * device/include/Makefile.in (version 1.11): in target 'install'
4463 added lines to copy all header files to installation path,
4464 * in target 'installdirs' added line create directory for pic16
4465 headers in the installation path
4467 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4480 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4481 option so that it actually works. Made it specific to the z80, since
4482 the gbz80 doesn't have these kinds of I/O ports.
4484 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4486 * device/include/z180.h,

4499 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4501 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4502 changed interrupt vector table generation to only emit declared vectors.
4503 * device/include/Makefile.in: added missing backslash
4504 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4506 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4508 Mainly changes to support compilation of the device libraries
4509 * src/pic16/device.c: stack is allocated via symbol and not
4510 via literal number. The symbol is placed in the corresponding
4511 position of the data ram
4512 * (pic16_dump_section): relocatable and absolute uninitialized
4513 data are now emitted in sorted order to reduce section naming,
4514 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4515 weren't marked as being in the access bank,
4517 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4519 Added portion of GNU PIC Library under the directory
4520 device/include/pic16 and device/lib/pic16. These files
4521 contain the declarations of SFRs for the PIC18Fxx2 devices.
4522 The directory is initialized via configure from toplevel.
4524 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4526 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4527 the spilllocations to be compared correctly

4549 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4551 * doc/sdccman.lyx: Moved and added some sections, small changes
4552 all over. Telling LaTeX to be less strict with word spacing
4553 to better keep the right margin. Changed some notes about
4554 maintainance of the ports in section 3.2.1 - is it OK like this?
4556 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4593 UPPER for immediate operands,
4594 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4596 * src/pic16/peeph.def: all peepholes with movff are commented out,
4597 because there is a problem in the pcode peep optimizer,
4598 * src/pic16/ralloc.c: the register allocator can now reuse local

4600 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4602 Added file src/pic16/NOTES with information about program writing on
4603 the current port version.

4662 * (pic14emitOverlay): modified to emit a commented overlay segment
4663 directive when no overlay data exist
4664 * (picglue): modified to emit uninitialized data segment
4665 according to udata_section_name

4675 2004-01-07 Borut Razem <borut.razem AT siol.net>
4677 * support/scripts/sdcc.nsi: update PATH
4678 * support/scripts/sdcc.ico: craeted

4691 include information about variables allocated to the overlay
4694 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4696 * as/mcs51/lkmain.c: Help about -Y option

4708 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4710 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4711 (default behaviour).
4713 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4715 A python script to validate compiler diagnostic messages. It can be
4716 used to verify that sdcc complains about bad c source code and
4717 gives a good location of the error.
4718 * support/valdiag/Makefile,
4719 * support/valdiag/valdiag.py,
4720 * support/valdiag/tests/*

4737 Bug reported from Jesus Calvino-Fraga
4739 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4741 * sdcc.spec: updated
4742 * device/include/Makefile.in: don't install CVS directories
4743 * device/lib/Makefile.in: added removal of CVS directories after install
4744 * doc/Makefile: fixed install, added local_icons
4745 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4746 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4747 * src/ds390/gen.c (genRightShift): fixed bug #870788
4748 * src/SDCCast.c (decorateType): fixed bug #870781
4750 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4752 PIC16 port related changes:
4753 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4754 added variable stackPos,
4756 * gen.c: genCall, assignResultValue: added support for
4757 pushing/retrieving function parameters to/from stack,
4758 genFunction,genEndFunction: setup stack frame for the
4760 genAddrOf: will be changed according to bug 863624
4762 * added files genutils.c and genutils.h which contain gen*
4763 debugged and optimised functions extracted from gen.c
4765 * glue.c: added variable 'externs' which holds extern symbols,
4766 pic16emitRegularMap: is modified to properly handle relocatable
4767 symbols under the new scheme,
4768 pic16createInterruptVect: is modified
4769 pic16printPublics: is modified to emit 'global' assembler directives,
4770 added pic16_printExterns to print extern symbols,
4771 pic16glue: initializes stack/frame pointer in the beginning of
4772 the assembly output. Temporary hack, will be corrected later,
4773 because gplink yet does not support stack and SDCC does not
4774 yet support a type of crt0.o object to create the final binary.
4776 * Removed many lines that contain 8051 legacy code.
4777 * The code is finally placed under a 'code' directive.
4778 * Added port specific options.
4780 * _process_pragma: simplified since now we do not need *special*
4781 include file to define SFR registers. But a separate header
4782 will be needed. This will be developed later.
4783 * _pic16_parseOptions: added, parses port specific options:
4784 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4785 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4786 --preplace-udata-with=
4788 * _pic16_setDefaultOptions: modified to initialize section names,
4789 but hack is temporarly out of order since it needs improvement.
4790 * _pic16_genAssemblerPreamble: configuration words are emitted by
4791 their address instead of their name. This part is incomplete and
4792 supports only the 18Fxx2 devices. Other devices will emit an error
4793 during assembly since they do not contain the same set of config
4795 * _pic16_genIVT: is modified,
4797 * pcode.c: added definitions for some hardware registers that are needed
4799 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4800 All PCI entries are updated. Now LFSR is supported.
4801 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4802 * added pic16_newpCodeOpLit2 to support instructions with
4803 two literal arguments
4804 * pic16_pCode2str: corrected code that emits assembler instructions
4805 with two literal operands and those that have an access bit modifier
4806 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4807 this fixes a bug which caused some labels to be lost, when an
4808 assembler directive was added, i.e. banksel,
4809 * pic16_FixRegisterBanking: improved logic that causes the insertion
4811 * InlineFunction: functions that are called once, are not any more
4812 inlined. This can be a port option in the future,
4814 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4816 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4817 hold the corresponding uninitialized symbols,
4818 * pic16_allocProcessorRegister: registers have explicit marked the
4820 * pic16_allocInternalRegister: registers are explicit marked as
4822 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4823 processing list, so bit registers were lost,
4826 * ralloc.h: added field 'accessBank' and original symbol operand
4827 in register definition,
4828 * removed the field isMapped from register definition,
4830 ** Several functions have been removed from various sources:
4831 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4832 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4833 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4834 pic16_assignRelocatableRegisters
4836 ** others have been introduced:
4837 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4838 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4840 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4842 * support/scripts/inc2h.pl: changed definition of BIT_AT
4843 to emit 'sbit at' instead of 'bit at'. This was a request.
4845 PIC16 port related preliminary changes:
4846 * gen.c: prefixed function popRegFromString with
4847 pic16_ and all references to it corrected
4848 * pcode.c: all pic16_pc_* hardware registers prefixed
4849 with underscore (_),
4850 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4851 * ralloc.c: newReg(): when register is REG_SFR then
4852 set address to rIdx,
4853 pic16_allocProcessorRegister(): marks register wasUsed=0
4854 pic16_writeUsedRegs(): added a call to assign processor
4855 registers via pic16_assignFixedRegisters
4857 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4859 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4860 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4861 variables in unused register banks. Also the SSEG is placed
4862 wherever there is enough space for it, and IDATA can be anywhere
4863 in internal RAM. For now compile using -Wl-Y[stack_size].
4864 The mem file is different for this option as well, since it
4865 makes no sense of talking about DSEG lenght.
4867 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4869 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4870 in certain cases, e.g. when ROM assignment, patch provided
4871 from Albert den Haan.
4873 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5426 not occur if the control variable is involved with a
5427 relational operator.

5916 A few small changes that speed up the peephole optimizer.
5920 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5922 Try to make the peephole optimizer smarter by maintaining
5923 an association between the assembly source code and the
5924 iCodes that originated them. Put this information to use
5925 with a new peephole rule condition "notVolatile" so that
5926 the rules can be aggressive yet still safe.
5931 * src/mcs51/peeph.def
5933 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5937 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5938 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5939 if the left or right operand symbols have the accuse flag set.
5941 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5943 Changed the type of the result of the ! (NOT) operator to char;
5944 previously it returned the same type as the source. This allows
5945 us to eliminate all the genFloatNot functions (all of its target
5946 implementations were very buggy) since !float can use the same
5949 * src/SDCCicode.c (ast2iCode): ! returns char

5958 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5959 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5960 during interrupts. Ensure WSAVE is located at a shared bank address.
5961 2. Fixed page selection in some places
5962 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5963 the registers name strings.
5964 4. Fixed "signed / unsigned compare" compiler warnings.
5965 5. The PIC port manages its own allocation of the general purpose
5966 registers, but makes no attempt to reuse them. As a result when
5967 compiling it soon runs out of general purpose registers. Some
5968 additional code was added to the files pcode.c and device.c to walk
5969 through the function call tree and rename the registers so that they
5979 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5986 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5988 Made bitfield a distinct type from bit so that bitfields
5989 convert as per ANSI C and bits retain their traditional
5990 boolean style behaviour. Implemented bitfield support in
5998 * src/ds390/gen.c: bit v bitfield split
5999 * src/z80/gen.c: New support for bitfields
6000 * support/regression/tests/bitfields.c: reenabled z80,
6003 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6005 Rules 246.x, 247.x relate to bitfields, the others speed up
6006 access to xdata mapped I/O devices.
6008 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6010 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6012 Cleaned up genPackBits and genUnpackBits and added two helper
6013 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6014 for literal assignments in genPackBits (thanks to Frieder for
6020 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6022 Fixed bug #748310 (pointer to function type mishandled when the
6023 function name is omitted). Also fixed a SIGSEGV when a function
6024 attribute (reentrant, etc) is used on a non-function or on a
6025 function but misplaced before the parameter list.

6052 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6054 Made the constant following the "interrupt" keyword optional. If
6055 omitted, the function will not automatically be given an entry
6056 in the interrupt vector table (similar to #pragma NOIV, but
6057 less syntacticly kludgy). The interrupt number is also now
6058 range checked. Also fixed a bug in the high order bit example

6534 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6535 the regression tests I'm not brave enough to enable 245.b, 245.c
6536 * doc/sdccman.lyx: added latex preamble for hyperref package.
6537 Using pdflatex this will give you a hyperlinked pdf file with
6538 bookmarks. (prepend '%' before /usepackage if this breaks something)

6579 it can be defined with CFLAGS when running configure
6580 * src/SDCCmain.c: fixed compiling + linking with object files
6582 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6585 added --disable-pic16-port
6586 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6587 * src/SDCCmain.c: linkOptions is changed to set *,
6588 added if/endif conditional macros to remove options help
6589 messages from optionsTable when a port is not configured, added
6590 support for the PIc16 port in the ports table, when executing
6591 the compiler with no port specified on command line, a default
6592 port is selected with the new macro DEFAULT_PORT which is
6593 defined in port.h, in setDefaultOptions() linkOptions is removed
6594 from initialization assignment, since now it is a set,
6595 parseCmdLine uses setParseWithComma for linkOptions, in
6596 linkEdit() linkOptions are accessed with new function indexSet()
6597 which returns the i'th item of a set variable. See SDCCset.c, in
6598 linkEdit() when calling buildCmdLine(), added linkOptions as
6599 last argument. Now users can pass arguments to gplink via the
6600 -Wl option, main() uses pic16glue() to glue up pic16 programs

6612 * src/pic16/glue.c: commented out some error producing lines
6613 * src/pic16/main.c: __config directives are commented out to stop
6614 gpasm complaining and test the linkage with gplink, _linkCmd and
6615 _asmCmd changed to be more gplink and gpasm friendly
6616 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6617 produced an error when parsed, peep rule 12 is added to utilize
6618 movff, but it is commented out since the pCode does not support
6619 yet a command with 2 address arguments
6621 2003-05-18 <johan AT balder>
6623 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6648 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6650 2003-05-11 Borut Razem <borut.razem AT siol.net>
6652 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6653 the path of bin directory, so that PATH is the only env. variable, which has to be set
6654 in case of standard installation.
6655 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7658 * src/SDCCicode.c: fixed array add
7660 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7661 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7662 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7664 2003-01-04 <johan AT balder>
7666 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7668 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7669 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

7681 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7682 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7684 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7686 * in \sdcc\as\mcs51\ changed these files in order to create an
7687 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7688 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7689 following files to include the previous two files: aslink.dsp,
7690 Makefile.aslink, Makefile.bcc, and Makefile.in.
7692 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7693 .adb instead of .cdb
7695 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7697 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7698 value from option --iram-size.
7700 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7702 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7705 2002-09-18 <wiml AT hhhh.org>
7707 * SDCClrange.h: exposed setFromRange() and setToRange()
7708 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7709 packRegsForAccUse() (bug 542397)
7710 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7711 multiple times and emitting the fetch operations more than once
7712 added aopGetUsesAcc() function to allow binary operators to
7713 fetch their operands in the correct order; made genMinus() emit
7714 compact code for X = LITERAL - Y
7716 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7717 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7718 sprintf() in line 1267.
7720 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7721 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7724 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7725 Changes to aslink (All the changes are marked with 'JCF'):
7727 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7730 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7731 area BSEG. Also moves, if possible, the DATA area down into the internal
7732 ram so more space is available.
7734 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7737 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7738 not bytes. Function summary() which creates a memory usage summary
7739 file with extension .mem. Reports of overlaping stack and small stack
7740 size. If the space for the stack is less than 16 bytes aslink trows a
7743 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7744 the 8051. Option 'y' for memory summary output file.
7746 Changes to sdcc (All the changes are marked with 'JCF'):
7748 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7750 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7751 overlaying area for it (uses RegBankUsed[4]).
7753 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7754 bank zero as used by default. By default aslink locates the stack
7755 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7756 the creation of the .mem file. Delegates the allocation of data area
7757 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7758 the begining of the stack area to aslink.
7760 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7761 glue() in SDCCglue.c creates an area for it.
7763 2002-09-03 Borut Razem <borut.razem AT siol.net>
7764 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7765 sdcc/src/pic/glue.c:
7766 introduced atexit() handler for teporay files removal in case of
7767 errors, assertions, ...
7769 2002-08-29 Borut Razem <borut.razem AT siol.net>
7770 * sdcc/support/cpp2/auto-host_vc_in.h:
7771 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7772 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7773 Maybe there is a similar problem with BORLANDC? It should be checked!
7775 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7776 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7777 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7778 was not executed, and the compiler (cl) launched a warning:
7779 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7781 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7782 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7784 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7785 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7787 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7788 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7789 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7790 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7791 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7792 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7793 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7794 - added Release configuration in VS projects
7795 - review of compiler an linker options
7796 - VC .exe files are generated in bin_vc directory, not to interfere
7797 with binaries generated from other projects (cygwin, mingw, bcc ...)
7799 * sdcc/src/yacc.dsp: added
7801 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7802 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7803 and insert the version number definitions from .version
7805 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7807 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7808 added - genarate auto-host.h using auto-host_vc_in.h as template
7811 removed from CVS, generated automatically
7813 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7814 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7816 2002-08-11 Borut Razem <borut.razem AT siol.net>
7817 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7819 2002-08-10 Borut Razem <borut.razem AT siol.net>
7820 * src/SDCCmain.c (main):
7821 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7822 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7823 The consequence was that some temporary files were not removed.
7826 unification of code in functions tempfilename() and tempfile():
7827 function tempnam() is defined in Visual Studio 6.0 and .NET
7829 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7831 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7832 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7833 - removed compiler command line option /WX: Treats all warnings as errors
7834 - update a list of source files, included into the project
7836 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

7850 added newline in the def file to keep MSC compiler satisfied
7852 * sdcc/src/z80/gen.c:
7853 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7854 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC

8034 * sdcc/src/SDCCloop.c:
8035 Previous fix was not good. basic blocks that have "break" or "return" are
8036 not really partof a loop , but live ranges used in these blocks should
8037 be live thru the entire loop, so set partOfLoop but don't add them to
